Back in September, Canon announced two new professional 4K, HDR, reference monitors – the Canon DP-V2420 (shipping now) and the DP-V1710 (shipping February 2017). I managed to get some hands-on time with the top-of-the-range DP-V2420 this week. Read on to see my thoughts on how the Canon DP-V2420 HDR Monitor performed. Features With a hefty £25k price tag, you’d expect the Canon DP-V2420 to be stuffed full of cutting edge display technology, and thankfully it is: 24-inch, 4096 x 2160, 4K, 10-bit, IPS LCD panel, with 178° viewing angle. Support for 48p, 50p and 60p source frame rates in 4K. ITU-R BT.709 and ITU-R BT.2020 colour gamut ITU-R BT.2100 and SMPTE ST 2084 compliant, supporting both Dolby Vision and HLG (Hybrid Log-Gamma). Peak luminance of 1200 cd/m2 and a minimum luminance of 0.005 cd/m2. Built-in 4K RAW de-bayer (from C300 mk2, C500 or C700). HDR-SDR Split-Screen View. How Does the Canon DP-V2420 Perform? As mundane as it may seem, the first thing that struck me when setting up the Canon DP-V2420 HDR Monitor was how simple and intuitive the menu system was. Having worked with a lot of reference monitors in my time, this was by far and away the easiest menu system I’ve come across. It was particularly quick and easy for me to create an HDR preset to match YouTube’s new HDR specification, with a peak luminance of 1000 cd/m2. The Canon DP-V2420 HDR Monitor menu. The next thing I noticed was just how crisp and defined the 4K image was. The material I was working with was originally shot on a RED Epic-W with the 8K Helium sensor, though I was working from a 4K Pro Res 4444 XQ master. The image quality was simply remarkable, but what truly blew me away was when I set my Resolve project to 1080p to test the DP-2420’s ‘Shape Tracing’ upscaling technology. I thought this would be a useful real world test, as not everyone has the required hardware to output 4K from their system, such as Blackmagic’s UltraStudio 4K Extreme. Once I was outputting a 1080p signal to the DP-V2420, I took a step back and couldn’t believe my eyes. If I hadn’t known better, I would have sworn I was looking at the 4K signal still! It really is one of the best upscaled 4K images I’ve ever seen. I was a bit dubious when I first heard that this monitor used a backlit LCD rather than an OLED panel. For HDR, one would normally expect OLED in order to achieve the low 0.005 cd/m2 blacks necessary. As soon as I was feeding it my signal, though, it became clear that Canon had achieved something truly unique with this backlight technology. The DP-V2420 HDR Monitor’s backlight scanning uses a full array RGB backlight, allowing individual areas to be partially turned off. Canon wouldn’t tell me too much about how this technology works, but it’s clearly very clever and produces deep blacks that one wouldn’t normally see on a backlit IPS panel like this. As well as local dimming, the sensors behind the backlight array are also able to measure temperature, luminance and colour information across the panel. This wealth of data allows the monitor to maintain optimal performance at all times and Canon even told me that it should mean that, under normal conditions, it shouldn’t require re-calibrating (it’s initially done using top-end Klein probes by Canon before it leaves their factory) before a year or more in to it’s working life! My only real criticism of this display is its fan noise. There were times when I thought the thing was going to take off! However, after chatting with Canon about this, I was told there is a firmware update coming soon to fix this issue. There will also be some new features introduced, the most exciting of which is the ability for the monitor to take an incoming feed and split it in two on screen, allowing the colourist or DIT to check both the HDR and SDR versions of the grade side by side. This is currently only possible by bridging the SDI In and Out ports on the back with an additional cable, but the update will remove this requirement, making it much easier to take advantage of this feature. I can see this split-screen feature, coupled with the HDR-compatible waveform monitor built into the Canon V-2420, as being extremely useful on-set during HDR productions. Summary In the burgeoning market for professional HDR monitors, the Canon DP-V2420 HDR Monitor is one of the ones leading the pack. It has some very clever tech inside it and several killer features that would make it invaluable both on set during an HDR shoot and in the colour suite. *Thanks to Abandon Visuals for allowing me to show their footage being used in this review.Read more

As of yesterday, Youtube has started to support HDR video. It is a step forward in implementing new technologies to web streamed videos, although at the moment only a handful of devices can really enjoy this new exciting feature. However, more supported TVs and displays are coming soon. “The World in HDR” from Jacob + Katie Schwarz (Youtube) YouTube seems to be always making first steps towards new technologies. We have seen this in the past with 4K video, live streaming, 360-degree video and many more features. This time, they bring HDR support to their video streaming service. HDR stands for “High Dynamic Range”. To simplify, HDR videos have higher contrast and clarity, revealing more detail in the shadows and highlights. Also, support for wide color gamut has been implemented, meaning that colours are more vibrant. For a closer look at “What HDR video is”, please head to a previously published video we made last year. Simulated HDR vs SDR comparison (truly visible only on HDR displays) Youtube HDR video compatible devices You can now watch YouTube videos in HDR on supported devices, such as HDR TVs with Google’s new Chromecast Ultra, Sony PlayStation 4 Pro Gaming Console and soon on all Samsung SUHD and UHD TVs 2016 models as well. If you’re using a device that doesn’t yet support HDR, videos will play in standard dynamic range. As more HDR devices become available, YouTube will work with partners to enable streaming of the HDR versions. If you want to watch some YouTube HDR video content today, you can check the following YouTube channels: MysteryGuitarMan Jacob + Katie Schwarz Abandon Visuals YouTube have worked together with these creators to bring HDR content in time for the HDR support launch. Starting today, any creator can upload HDR videos to YouTube. You can learn more about uploading HDR videos here. It is worth mentioning that YouTube team worked together with the DaVinci Resolve team to make uploading HDR content just as simple as SDR videos. They’ve also outfitted the YouTube Spaces in LA and NYC with all the gear needed to produce high quality HDR content. Ed Khoma from Abandon Visuals responded to our request to highlight the new YouTube HDR support and here is what he had to say: HDR implementation is revolutionary to our industry and we believe that it is the next evolution of content streaming. It gives content creators the power to show their viewers a new visual experience by expanding the range of color and data that was once sacrificed. We are honored to be a part of the launch for Youtube’s HDR support and are excited for a future with HDR-capable monitors and online streaming.” You can watch Ed Khoma and Jonny Mass’s HDR short film on YouTube here: Do you already have an HDR supported device?
